摘要

Background People after stroke have difficulties when they undertaking two tasks simultaneously. Purposes To investigate the relationships between dual-task performance and factors such as motor function, balance, cognitive state, and fatigue, to identify factors that have an impact on dual-task performance after a stroke. Methods Thirty-seven people with stroke and 38 healthy participants were assessed with 10-m walking test in different performances which were single-task-based, motor dual-task-based and cognitive dual-task-based. Results were evaluated according to the Rivermead Motor Assessment, the Static balance index, the Mini-Mental State Examination, and the Fatigue Severity Scale. Results Participants with stroke were slower compared to the control group with the following mean speed values for single-task (M = 0.73 m/s, t = -7.612,p< .001), motor dual-task (M = 0.70 m/s, t = -8.232,p< .001), cognitive dual-task (M = 0.59 m/s, t = -7.944,p< .001). For people after stroke, motor dual-task performance was significantly affected by the total motor function scores (r = 0.648,p< .001), static balance (r = -0.499,p< .05), and fatigue rates (r = -0.349,p< .05). Furthermore, cognitive dual-task performance was affected by the total motor function score (r = 0.537,p< .05) static balance (r = -0.541,p< .05) and fatigue rates (r = -0.350),p< .05). Multivariate factor analysis indicated that impairment in the gross function influenced motor dual-task performance (B = 0.086,p= .031) and cognitive dual-task performance (B = 0.083,p= .010). Cognitive dual-task performance was affected by leg-trunk function (B = 0.063,p= .015) and age (B = -0.006,p= .009). Conclusion The present study indicated that dual-task performance was related to motor function, balance, and fatigue, whereas gross motor function was the unique determinant of dual-task performance.
